Abstract: A method for locally modifying a structure of a paperboard. A penetrating region (114) of the paperboard (110) is penetrated by laser radiation (102) such that moisture in the penetrating region (114) evaporates for locally modifying the structure of the penetrating region (114) e.g. by weakening the paperboard at the region and for deforming it there.

Abstract: A lateral positioning device (100) for a sheet element (20, 20′) in a sheet element processing machine; a detector lever (130) articulated relative to a horizontal axis, which performs a descending movement from a high position to a low position; a first end (132) of the detector lever (130) contacts, in a low position of the lever, with an upper face of the sheet element. A second end (133) of the detector lever (130) is fitted with a target (135) that cooperates with a position detector (140) to generate a signal dependent on the thickness of the sheet element (20, 20′) and the number of sheet elements (20, 20′) present at the level of the first end (132) of the detector lever (130).

Abstract: A device for printing a succession of sheets, includes a platen press for depositing colored or metalized film on each sheet by stamping between a stationary platen and a movable platen. A heating element brings a stamping tool integral with the stationary platen to a given temperature for a stamping operation. The heating element is displaced between an operating position, which is between the stationary platen and each stamping tool associated with that platen, and a maintenance position in which the heating element is outside the platen press.
